Abstract

In this study, the ferroresonance phenomena are
considered under the modeling of the West Anatolian
Electric Power Network of 380 kV in Turkey. The
ferroresonance event is carried out using the switching to
remove the loads at the end of the lines. In this sense, two
different cases are taken. At first, the switching is applied
at 0.5 second and the ferroresonance effects are observed
between 0.5 and 1 second in terms of the voltage
variations. As a result the ferroresonance case and steady
state case before the ferroresonance are compared with
each other using the Fourier transform techniques. Hence,
the properties of the ferroresonance event, which are
defined between the 125 and 250 Hz, are presented in the
frequency domain.
